In a little more than a year, 15 Central Park West has become the city’s toniest address. A collection of about 200 apartments full of moguls, movie stars and rockers, it’s the kind of place where your mail could get mixed up with a NASCAR driver or the head of a Wall Street bank.

Estimated combined net worth — $50 billion.

“It’s the contemporary analog to 740 Park,” said author Michael Gross, comparing 15 CPW with the legendary Park Avenue high-rise that he, in his 2005 book, dubbed “the richest building in New York.”

“It’s a palace for the latest iteration of the new rich.”

The Zeckendorf brothers, William and Arthur, built the Robert A.M. Stern-designed high-rise on a $400 million piece of fallow land on Central Park in 2007. They made $2 billion on the gamble.

“They took a huge bet, and they won. They built their building and got their money out,” Gross said.

“But I bet a lot of people in that building are extremely nervous now. The people who bought there all have their money on the table, and the game isn’t over yet.”

“In the market of trophy modern buildings, of which there are only three, it’s No. 1,” said broker John Burger, counting 2 Time Warner and 1 Beacon Court as the other two.

The building is divided into two parts — the 40-story “tower,” with grand views of the city, and the 20-story “house,” which is closer to the park.

Through property records and interviews, The Post compiled a list of movers and shakers who call 15 CPW home:
